I have a couple of questions about bitrate.

  1. ARE THERE BLU-RAYS DONE AT 16MBPS?
    If H.264 can re-encode 8mbps DVD down to 2.5mbps with no noticeable drop in quality, couldn’t you get Blu-Ray quality video at 16mbps? Are there any movies on BluRay that have done this?
  2. WHAT ARE 4K BITRATES LIKE?
    What’s the average bitrate of a 4k Blu-Ray? I’ve heard it’s usually around 42mbps, which makes sense calculating it up from the 33.5mbps of many regular Blu-Rays. (factor​ing in the quadrupled resolution, 12-bit color space, and efficiency of h265.), but taking my 16mbps theory into account, could 4k be done at 26mbps? or is that just blasphemy?
